[sysest,simout] = frestimate(mdl,io,in);Perform exact linearization, and compare to the estimated response.sys = linearize(mdl,io);
bodemag(sys,sysest,'r*')The estimated frequency response does not match the exact linearization. The mismatch
occurs because time-varying source blocks in the model prevent the response from
reaching steady state.Find the time-varying blocks using frest.findSources.srcblks = frest.findSources(mdl);15 Alphabetical List
